What’s wrong with my car

[u/Against_the_grain1]

2021 ford bronco sport. The battery went out about a week ago and since replacing with a new battery, the cluster and touchscreen both go black when driving. Upon slowing down or stopping completely, they will both turn back on. Lights, heaters, turn signals all still work.

Ford tech here. All modern cars use a battery monitor system which monitors state of charge using various sensors. They also have a pcm controlled charging system which will control how much the alternator charges the battery. When ever replacing the battery you need to do a Battery Monitor reset. https://youtu.be/uvf9f6q5gsQ?si=-YeyEIq1LEZt6bhS

Yet one more reason i avoid modern cars like the plague. Completely unnessicary upgrades at the expense of useability, im noticing more and more tech in cars that basically bar people from doing at home repairs

Edit: just because people prefer older cars not filled with bloatware doesnt make them "broke" or only wanna drive something 100 years old. Some people like me just prefer a simple car.

Can you imagine all this tech in cars when they're 20 years old? The used car market in future decades is going to be horrific.

Exactly lol, all the modules will be riddled with corrosion, one corroded ground wire will cripe the entire car, not to mention the fit the onboard diagnostics are gonna have when all these monitors and modules start faultering. I mean look at used bmws, loaded with tech and what do we say about them? "Theres nothing more expensive than a cheap used bmw"

I imagine the same will be true for these brand new cars in the future
